Drop It (Ignore the Remainder)

• Mrs. Bushell is organizing her recipes into a binder. Exactly 4 recipes fit on each page. She has 22 recipes. How many pages will Mrs. Bushell fill?

• 22 ÷ 4 = 5 R 2

• What does the 2 represent? The 2 is the extra recipes that will go on a new page, but that page will not yet be filled.

• What does the 5 represent? The number of pages that will be completely filled. 

• In order to answer the question, I need to DROP the remainder. 

• Mrs. Bushell will fill 5 pages.

Add One (Add 1 to the quotient)

• Mrs. White is buying cupcakes for her class. The cupcakes come in boxes of 4. There are 22 students in her class. How many boxes of cupcakes does Mrs. White need to buy if she wants to give each student a cupcake?

• What does the 5 represent? At least 5 boxes of cupcakes will need to be ordered.

• What does the 2 represent? The number of students who would not get a cupcake if only 5 boxes of cupcakes are ordered.

• I need to ADD 1 so that everyone gets a cupcake. Instead of 5 boxes of cupcakes, she needs to order 6 boxes.  (6x4=24, so everyone gets a cupcake)
